Answer:

Suppose any object with mass in our planet.

The object will be affected by the gravitational force, that pulls the object down. Now, a table in your dining room is also affected by this force, but the table is in a surface (the ground) and it does not move.

We know that if an object does not move, then the net force acting on it is equal to zero, this means that there is a force equal and opposite ot the gravitational force.

This force is the normal force, that the ground applies on the table. This force comes as a "response" to the table pushing the ground (By 3rd Newton's law).

So two forces that are always equal and opposite are the forces caused by this law.

This pair of pucks will rotate at the same rate.

Hover Puck:

The Hover Puck coasts effectively on a self-produced pad of air until followed up on by an outside power.

Employments of hover puck:

The Hover Puck coasts effectively on a self-produced pad of air until followed up on by an outside power.

• Use one Hover Puck to show themes from Newton's First Law to impacts to reflection.

• Use at least two pucks to examine the protection laws in two measurements.

• Set up a bowling alley utilizing plastic beverage bottles.

Innovation of hover puck:

The First Rubber Hockey Pucks Were Made From Sliced-Up Lacrosse Balls. At the point when the game moved inside, entire balls were initially utilized, yet arena proprietors before long thought that it was desirable over cut them into thirds and keep the center segment. This fundamental plan was the standard by 1885.

hockey puck was developed:

The hockey puck appeared in 1875. It's hazy who really imagined it. Specialists accept the main hockey puck was likely only an elastic ball cut down the middle. This gave players an article with a level side that would slide over the ice.

In which of these samples do the molecules most likely have the most kinetic energy? (2 points)

Vinvika [58]

D, water vapor. Gaseous state would have more kinetic energy, they are moving faster. If you have to compare the same state, then higher temperature would have the higher kinetic energy. But if you have solid and liquid at the same temperature - then liquid would have more.

Name and describe at least SIX engineering challenges that the Mars copter, Ingenuity, had to overcome in order to be built/to t

Y_Kistochka [10]

Answer:

Explanation:

1. Ingenuity is a flight test.

Ingenuity is what is known as a technology demonstration – a project that seeks to test a new capability for the first time, with limited scope. Previous groundbreaking technology demonstrations include the Mars Pathfinder rover Sojourner and the tiny Mars Cube One (MarCO) CubeSats that flew by Mars in 2018.

Ingenuity features four specially made carbon-fiber blades, arranged into two rotors that spin in opposite directions at around 2,400 rpm – many times faster than a passenger helicopter on Earth. It also has innovative solar cells, batteries, and other components. Ingenuity doesn't carry science instruments and is a separate experiment from the Mars 2020 Perseverance rover.

2. Ingenuity will be the first aircraft to attempt controlled flight on another planet.

Slove the following equation for v <br> A=v/t

LenKa [72]

If you meant solve, the answer would be v= A times t

You see, to get rid of an variable on one side, you must do the opposite of what is being done to it, in this case, multiply because division. After this, we must do what we did to one side to the other side. This creates the equation above!
